When purchasing it thought that it can be used in conjunction with a corner sponge (holding bella), at the time of work that puts a corner at the corner while pressing the cloth with a wire, force is not applied uniformly, it is very easy to break. Also, since the tip is thick and the angle is not so good, it is difficult to put out the corner etc.
I put a corner with a spatula, but it can be used to be used for the back of a toilet bowl that can not hold down without cutting down on the ground.
If it is a craftsman who does not use a spatula, it is a product that its accuracy may increase slightly.
As an improvement point, I did not substitute a spatula with a wire, but I thought that it would probably be usable if I stretched the base part of the cutter and attached a proper flat spatula.
Furthermore, if you do not make more edges at the tip, it will not reach the corner where three points (wall ceiling etc.) intersect.
